Description

Technical Field

[0001] The present application relates to the technical field of water treatment equipment, and in particular to a filter element assembly and a mineral water purifier. Background Art

[0002] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Mineralized water is a kind of water containing mineral salts, rich in macro- and trace elements necessary for the human body. Therefore, mineralized water is favored by people as drinking water. At the same time, there is a certain demand for mineralized water containing specific mineral salts during production and experiments.

[0003] At present, there are two common ways to prepare mineralized water. The first is to artificially mix mineral salts and water into mineralized water of appropriate concentration, but this method is very troublesome, has a certain threshold of chemical knowledge and is inefficient. The second is to put ore containing mineral salts into a container filled with water, such as a drinking fountain or a water purifier. The mineral salts in the ore can dissolve into the water in the container, turning the water into mineralized water. However, it is difficult to effectively control the mineral content of the mineralized water prepared by this method. Many mineral salts themselves have poor solubility and are difficult to dissolve from the ore, resulting in the water in the container not containing enough mineral salts after directly soaking the ore.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Mineralized water is a kind of water containing mineral salts, rich in macro- and trace elements necessary for the human body. Therefore, mineralized water is favored by people as drinking water. At the same time, there is a certain demand for mineralized water containing specific mineral salts during production and experiments.

[0032] At present, there are two common ways to prepare mineralized water. The first is to artificially mix mineral salts and water into mineralized water of appropriate concentration, but this method is very troublesome, has a certain threshold of chemical knowledge and is inefficient. The second is to put ore containing mineral salts into a container filled with water, such as a drinking fountain or a water purifier.

[0033] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0034] See also Figure 1 to Figure 7 , Figure 1 A schematic diagram of the assembly structure of the filter element assembly provided in this application. Figure 2 A schematic cross-sectional structure diagram of an embodiment of a filter element assembly provided in the present application without promoting filter material and mineralizing filter material.

Figure 5 A schematic cross-sectional view of another embodiment of the filter element assembly provided in the present application without promoting filter material and mineralizing filter material. Figure 6 A schematic cross-sectional view of another embodiment of the filter element assembly provided in the present application. Figure 7This is an exploded cross-sectional structural diagram of another embodiment of the filter element assembly provided by the present application. A specific embodiment of the present application provides a filter element assembly 1 , including a promoting filter material 81 and a mineralizing filter material 91 .

[0035] The filter element assembly 1 is provided with an inner waterway 2, and the promoting filter material 81 and the mineralizing filter material 91 are connected in series between the water inlet 22 and the water outlet 23 of the inner waterway 2. The mineralizing filter material 91 contains soluble minerals, and the promoting filter material 81 contains a promoting substance that can promote the dissolution of minerals from the mineralizing filter material 91.

[0036] In the structure provided in this specific embodiment, the promoting filter material 81 and the mineralized filter material 91 are successively arranged in series in the internal water channel 2 of the filter element assembly 1. When the filter element assembly 1 continues to discharge water outward, the promoting substance in the promoting filter material 81 is normally dissolved into the flowing water. Since the mineralized filter material 91 is arranged downstream of the promoting filter material 81, the promoting substance flows to the mineralized filter material 91 along with the water, thereby promoting the minerals in the mineralized filter material 91 to be normally dissolved into the flowing water, thereby increasing the mineral content of the mineralized water output by the filter element assembly 1 under the flowing state.

[0037] In the soaking state where the filter element assembly 1 stops discharging water, the soaking water in the inner waterway 2 no longer flows through the promoting filter material 81 first and then through the mineralizing filter material 91. Although the soaking water no longer has a macroscopic flow trend, the mineralizing filter material 91 is actually connected to the promoting filter material 81, so that the promoting substance can also diffuse in the soaking water to move toward the mineralizing filter material 91, which can promote the dissolution of minerals into the soaking water, thereby increasing the mineral content of the mineralized water output by the filter element assembly 1 in the soaking state. The filter element assembly 1 structure provided by the present application can effectively increase the mineral content in the mineralized water regardless of the flow state or the soaking state, and reduce the probability of insufficient mineral content in the mineralized water, thereby improving the stability and availability of the filter element assembly 1.

[0038] Optionally, the promoting filter material 81 may include a weakly acidic filter material, such as a weakly acidic ore. The mineralized filter material 91 may include a calcium mineralized filter material 91 and a magnesium mineralized filter material 91, such as calcium-rich or magnesium-rich ores. The promoting filter material 81 can dissolve acidic substances in the water body, and the acidic substances can promote the dissolution of mineral elements such as calcium and magnesium in the mineralized filter material 91, thereby achieving the effect of increasing the content of minerals in the mineralized water.

[0039] In a specific embodiment of the present application, the filter element assembly 1 includes a filter cartridge 3, and a first accommodating cavity 8 and a second accommodating cavity 9 are sequentially arranged along the direction of the inner waterway 2. The promoting filter material 81 is accommodated in the first accommodating cavity 8, and the mineralized filter material 91 is accommodated in the second accommodating cavity 9. The first accommodating cavity 8 and the second accommodating cavity 9 are arranged in the filter cartridge 3 along the axial direction of the filter cartridge 3.

[0040] In the structure provided in this specific embodiment, the first accommodating chamber 8 and the second accommodating chamber 9 are arranged along the axial direction of the filter cartridge 3, so that when the water body flows along the filter cartridge 3, it can sequentially contact the promoting filter material 81 and the mineralizing filter material 91. Regardless of the flow state or the immersion state, the promoting substance can be used to effectively promote the dissolution of minerals, so that the mineral content in the mineralized water output by the filter element assembly 1 is guaranteed, the probability of low mineral content in the mineralized water is reduced, and the stability and availability of the filter element assembly 1 can be improved.

[0041] In a specific embodiment of the present application, the first accommodating cavity 8 may be disposed above the second accommodating cavity 9 .

[0042] In the structure provided in this specific embodiment, the first accommodating chamber 8 is arranged above the second accommodating chamber 9. In the overflow state, the water body can enter the second accommodating chamber 9 through the promoting filter material 81 in the first accommodating chamber 8 under the action of gravity, and due to the existence of gravity, the probability of backflow is low and the filtering process can be promoted. In the soaking state, the water bodies in the first accommodating chamber 8 and the second accommodating chamber 9 can also flow to each other. Therefore, whether in the overflow state or the soaking state, the promoting material can be used to effectively promote the dissolution of minerals in the mineralized filter element, reduce the probability of low mineral content in the mineralized water, and thus improve the stability and availability of the filter element assembly 1.

[0043] In a specific embodiment of the present application, the filter element assembly 1 may include a first isolating member 4, and the first isolating member 4 is provided with at least one first through hole 41. The first isolating member 4 is disposed between the first accommodating chamber 8 and the second accommodating chamber 9, and the fluid in the first accommodating chamber 8 can enter the second accommodating chamber 9 through the at least one first through hole 41.

[0044] In the structure provided in this specific embodiment, the first isolation member 4 is used to separate the first accommodating chamber 8 and the second accommodating chamber 9, so that the water in the first accommodating chamber 8 can only enter the second accommodating chamber 9 through the first through hole 41, thereby utilizing the first through hole 41 to limit the flow of water between the first accommodating chamber 8 and the second accommodating chamber 9, such as controlling the flow rate, flow rate and flow direction, so that the water between the first accommodating chamber 8 and the second accommodating chamber 9 can flow evenly, thereby improving the stability and availability of the filter element assembly 1.

[0045] Optionally, the number of the first through holes 41 can be multiple, and the multiple first through holes 41 are evenly opened on the first isolating member 4, so that the fluid between the first accommodating chamber 8 and the second accommodating chamber 9 can flow evenly through the multiple first through holes 41. This can avoid the problem that the water flow between the first accommodating chamber 8 and the second accommodating chamber 9 is too concentrated, resulting in excessive flow velocity and severe scouring at a local position, thereby affecting the mineralized filter material 91 and promoting the service life of the filter material 81.

[0046] See also Figure 1 to Figure 4In a specific embodiment of the present application, the filter cartridge 3 may include an outer cartridge 31 and a first inner cartridge 32, wherein the outer cartridge 31 is sleeved on the outer periphery of the first inner cartridge 32. The first accommodating chamber 8 and the second accommodating chamber 9 are arranged in the first inner cartridge 32 from top to bottom, and the first inner cartridge 32 is provided with a first inlet 321 at the upper end and a first outlet 322 at the lower end. The water inlet 22 and the water outlet 23 are arranged at the lower end of the outer cartridge 31, the first outlet 322 is connected to the water outlet 23, and the first inlet 321 is connected to the water inlet 22.

[0047] In the structure provided in this specific embodiment, the first inner cylinder 32 is used to limit the mineralized filter material 91 and the promoting filter material 81, and the direction of the water flow in the overflow state can be controlled to flow from the first accommodating chamber 8 to the second accommodating chamber 9. The first inlet 321 is arranged at the upper end of the first inner cylinder 32, so that the water level between the outer cylinder 31 of the filter element assembly 1 and the first inner cylinder 32 must rise to the upper end of the first inner cylinder 32 to be immersed in the water before entering the first accommodating chamber 8 through the first inlet 321, and the water level in the filter element assembly 1 can be maintained so that the promoting filter material 81 can be fully in contact with the water body.

[0048] In addition, the first outlet 322 is arranged at the lower end of the first inner tube 32. The water entering the first accommodating chamber 8 through the first inlet 321 is filtered by the promoting filter material 81 and the mineralized filter material 91 under the push of the water pressure in the overflow state, and is also affected by gravity. Gravity can further improve the efficiency of the promoting filter material 81 and the mineralized filter material 91 in filtering the water, thereby making the promoting filter material 81 and the mineralized filter material 91 more fully contact with the water body, and using natural gravity to improve the working efficiency of the filter element assembly 1.

[0049] In a specific embodiment of the present application, the filter element assembly 1 further includes a second isolating member 5. The second isolating member 5 is provided with at least one second through hole 51.

The second isolating member 5 is covered with the first inlet 321, and the fluid in the first water inlet 21 can enter the first accommodating chamber 8 through the at least one second through hole 51.

[0050] In the structure provided in this specific embodiment, similar to the first isolation member 4, by setting the second isolation member 5, the water flow entering the first accommodating chamber 8 from the first water inlet 21 through the first inlet 321 can be controlled, and the second through hole 51 is used to limit the flow of water between the first accommodating chamber 8 and the first water inlet 21, such as controlling the flow rate, flow rate and flow direction, so that the water between the first accommodating chamber 8 and the first water inlet 21 can flow evenly, thereby improving the stability and availability of the filter element assembly 1.

[0051] Optionally, the second isolating member 5 may also be disposed between the second accommodating chamber 9 and the first outlet 322 , and the fluid in the second accommodating chamber 9 may enter the first outlet 322 through at least one second through hole 51 .

[0052] In the structure provided in this specific embodiment, similar to the first isolation member 4, the second isolation member 5 is used to separate the second accommodating chamber 9 and the first outlet 322, so that the water in the second accommodating chamber 9 can only enter the first outlet 322 through the second through hole 51, thereby utilizing the second through hole 51 to limit the flow of water between the second accommodating chamber 9 and the first outlet 322, such as controlling the flow rate, flow rate and flow direction, so that the water between the second accommodating chamber 9 and the first outlet 322 can flow evenly, thereby improving the stability and availability of the filter element assembly 1.

[0053] Optionally, the number of the second through holes 51 can be multiple, and the multiple second through holes 51 are evenly opened on the second isolation member 5, so that the fluid between the first accommodating chamber 8 and the first water inlet 21, and / or between the second accommodating chamber 9 and the first outlet 322 can flow evenly through the multiple second through holes 51. It can avoid the problem that the water flow between the first accommodating chamber 8 and the first water inlet 21, and / or between the second accommodating chamber 9 and the first outlet 322 is too concentrated, resulting in excessive flow velocity and severe scouring at a local position, thereby affecting the service life of the mineralized filter material 91 and / or promoting the filter material 81.

[0054] See also Figure 5 , Figure 6 , Figure 7 In a specific embodiment of the present application, the filter cartridge 3 may include an outer cartridge 31 and a second inner cartridge 33, and the outer cartridge 31 is sleeved on the outer circumference of the second inner cartridge 33. The second accommodating chamber 9 is disposed in the second inner cartridge 33, and the filter material 81 and the second inner cartridge 33 are disposed from top to bottom along the axial direction of the filter cartridge 3. The second inner cartridge 33 has a second inlet 331 at its upper end and a second outlet 332 at its lower end. The water inlet 22 and the water outlet 23 are disposed at the lower end of the outer cartridge 31, the first isolating member 4 is covered on the second inlet 331, and the second outlet 332 is connected to the water outlet 23.

[0055] In the structure provided in this specific embodiment, the second inner cylinder 33 can be used to cooperate with the first isolation member 4 to form a second accommodating chamber 9, thereby limiting the direction of water flow in the overflow state, and the second inlet 331 is arranged at the upper end of the first inner cylinder 32, so that the water level between the outer cylinder 31 of the filter element assembly 1 and the second inner cylinder 33 must rise to immerse the upper end of the second inner cylinder 33, and the water body can enter the second accommodating chamber 9 through the second inlet 331, which can maintain the water level in the filter element assembly 1, so that the promoting filter material 81 can fully contact with the water body, and then can dissolve a sufficient amount of promoting substance into the water body to promote the dissolution of minerals.

[0056] In a specific embodiment of the present application, the filter element assembly 1 may further include a first end cap 61, and a first central channel 82 is provided in the promoting filter material 81. The first end cap 61 and the first isolating member 4 are respectively provided at both ends of the promoting filter material 81. One end of the first central channel 82 is blocked by the first end cap 61, and the other end of the first central channel 82 is connected to the first through hole 41.

[0057] The first end cap 61 may be covered on the upper end of the promoting filter material 81 , and the first isolating member 4 may be covered on the lower end of the promoting filter material 81 .

[0058] In the structure provided in this specific embodiment, the first central channel 82 can be used to guide the water filtered by the mineralized filter material 91, thereby guiding this part of the water to flow into the second accommodating chamber 9 through the first through hole 41. The first end cover 61 can ensure that the water input into the first central channel 82 is filtered by the promoting filter material 81, so that this part of the water containing the promoting substance enters the second accommodating chamber 9 to promote the dissolution of minerals, which can improve the stability and availability of the filter element assembly 1.

[0059] In a specific embodiment of the present application, the filter element assembly 1 may further include a second end cap 62, and a second central channel 92 is provided in the mineralized filter material 91.

The second end cover 62 can ensure that the water input into the second central channel 92 is filtered by the mineralized filter material 91, and can also make the promoting substance in the water fully contact with the mineralized filter material 91. The minerals in the mineralized filter material 91 can be fully dissolved into the water under the promotion of the promoting substance, thereby effectively increasing the content of minerals in the mineralized water and reducing the probability of insufficient mineral content in the mineralized water, thereby improving the stability and availability of the filter element assembly 1.

[0064] Optionally, see Figure 2 to Figure 7 The filter element assembly 1 may include a docking member 7. One end of the docking member 7 docks with the second outlet 332 or the first outlet 322, and the other end of the docking member 7 is connected to the water outlet 23, so as to guide the water flowing out of the second outlet 332 or the first outlet 322, and separate the water outlet 23 from the first water inlet 21 in the outer cylinder 31, so that this part of the water can be smoothly output to the outside of the filter element assembly 1 through the water outlet 23, and reduce the probability of cross-flow, backflow and the like in the overflow state.

[0065] A specific embodiment of the present application provides a mineral water purifier for treating fluid. The mineral water purifier may include a device body and a filter element assembly 1 as described in any of the above specific embodiments. The device body can be connected to the water inlet 22 and the water outlet 23 of the filter element assembly 1 respectively.

[0066] In the structure provided in this specific embodiment, the promoting filter material 81 and the mineralized filter material 91 are successively arranged in series in the internal water channel 2 of the filter element assembly 1. When the filter element assembly 1 continues to discharge water outward, the promoting substance in the promoting filter material 81 is normally dissolved into the flowing water. Since the mineralized filter material 91 is arranged downstream of the promoting filter material 81, the promoting substance flows to the mineralized filter material 91 along with the water, thereby promoting the minerals in the mineralized filter material 91 to be normally dissolved into the flowing water, thereby increasing the mineral content of the mineralized water output by the filter element assembly 1 under the flowing state.

[0067] In the soaking state where the filter element assembly 1 stops discharging water, the soaking water in the inner waterway 2 no longer flows through the promoting filter material 81 first and then through the mineralizing filter material 91. Although the soaking water no longer has a macroscopic flow trend, the mineralizing filter material 91 is actually connected to the promoting filter material 81, so that the promoting substance can also diffuse in the soaking water to move toward the mineralizing filter material 91, which can promote the dissolution of minerals into the soaking water, thereby increasing the mineral content of the mineralized water output by the filter element assembly 1 in the soaking state. The filter element assembly 1 structure provided by the present application can effectively increase the mineral content in the mineralized water regardless of the flow state or the soaking state, and reduce the probability of insufficient mineral content in the mineralized water, thereby improving the stability and availability of the mineral water purifier.
